What loggers are being used?
More than 60% of reviewed literature used loggers made by Onset Computer Corporation. The dominant sensor was from the HOBO Pendant series with HOBO Pro’s closely following. Nearly 20% of studies did not identify which HOBO logger they used (“Not mentioned”, “HOBO”).
Of the studies using Sea-Bird Scientific, the second most common logger brand, models SBE 37 and 39 made up about half.
How are they being used?
For what and how often are measurements logged?
Studies were classified under 5 types, most of which were Ecology. Loggers were set to record measurements as low as once per 0.5 seconds (Physical Oceanography) to once per day (Biogeochemistry, Ecology), although ecological studies use a greater range of logging frequencies than any other study type.
